DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 670,821, dated March26, 1901.

Application iiled July 6. 1900. Serial No. 22,682. (No model.)

To all whom t may concern:

Be it known that I, GEORGE STUBBS, a subject of the Queen of GreatBritain, residing at Perth, in the Colony of Western Australia, haveinvented a new and Improved Door- Gheck, of which the following is afull, clear, and exact description.

The object of the invention is to provide a new and improved door-checkwhich is simple and durable in construction, cheap to manufacture, andarranged to form an ornament for a door, to permit the operator toconvenientlybring the check into action'for holding the door in an openposition, and to allow of moving it into an inactive position when it isdesired to freely open or close the door.

The invention consists of novel features and parts and combinations ofthe same, as will be fully described hereinaftei` and then pointed outin the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this speciiication, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure lis a perspective view of the improvement as applied and withparts in an active position to hold the door open. Fig. 2 is an enlargedtransverse section of the same. Fig. 3 is a section on line 3 3 of Fig.4L. Fig. 4 is an edge View of the operating mechanism for the check-boltwith the front part of the housing in section. Fig. 5 is an enlargedrear elevation of the check-bolt casing and retaining device for holdingthe parts in position for shipment, and Fig. 6 is a sectional plan viewof the same on the line 6 6 in Fig. 5.

The housings A and B are secured by screws or other means to the insideof the door C, as is plainly illustrated in Figs. l and 2, and the lowerend of the housing A is formed with a guideway A for a check-bolt D,preferably made of rubber or like elastic material, adapted to engagethe door when the door is open, so as to hold the door againstaccidental closing. The check -bolt D is secured on the lower end of arod E, extending vertically to `slide in suitable bearings A2 and B',formed ing A. A washer E is secured on the rod E within the housing A,and said washer is pressed on by one end of a spring F, coiled aroundthe rod E and resting with its upper end on the bearing A2, so that saidspring F exerts a downward pressure on the rod E and check-bolt D tohold the latter with the desired force in contact with the floor toprevent the door from accidentally closing.

The upper end of the rod E is pivotally connected with a lever G,fulcrumed on a pivot-pin H, carried by the housing B, said' pivot-pinextending through an elongated slot G' in the lever G to permit thelatter to swing and to slide on said pivotepin H. The shank of the leverG is adapted to rest on a shoulder B2, formed on one side of the housingB, adjacent to slot B3 in the housing B, aspring I pressing said leverat the time the latter is seated on said shoulder B2.

When the lever is in an uppermost position and is seated on the shoulderB2, then the rod E and the check-bolt D are likewise in their innermostpositions, the lower end of the check-bolt being Hush with the underside of the housing A and the bottom of the door `C to permit of freelyopening or closing th door in the usual manner.

When the door has been swung open and it is desired to lock the dooragainst accidental closing, then the operator takes hold of the free orhandled end G2 of the lever G and first moves the same forward off theshoulder B2 and then releases the lever to allow the spring F to movethe rod E and the check-bolt D downward to cause the check-bolt toengage the iioor, and thus hold the door against m0vement. During thedownward movement of the rod E a like movement is given to the lever G,which swings at its free end in the slot B2, it being understood thatthe lever Gduring its downward movement also slides with its fulcrum endon the pivot-arm H, and this movement is necessary owing to the verticalmovement of the rod E.

lVhen it is desired to unlock the door, then the operator takes hold ofthe end G2 of the lever Gand swings the same upward and seats the sameon the shoulder B2, thereby drawing the check-bolt D out of engagementwith the door, as previously stated.

IOO

When shipping the device, it is desirable one fork member a groove E2 insaid, rod, asV

is plainly indicated in Fig. 6. lThe, lockingplate J is adapted to reston the vtop of the 'housing A and engages the groove E2 at the time thecheck-bolt D is withdrawn, so that the several parts are held in thislocked position and the device can be readily shipped from one place toanother, it being, however, expressly understood that the plate J is notused and does not form part of the device after the device is onceattached to the door.

The housings A and B are placed a sufcient distance apart to permit theoperator to conveuienly manipulate the lever G, as described, andwithout assuming a stooping position.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- Al. A door-check, comprising a check-bolt, aspring-pressed rod carrying said check-bolt at one end, a leverpivotally connected with the other end of the rod and capable of slidingon its fulcrum, and means for holding said lever in a locked positionwhen said check-bolt is withdrawn against the tension of the spring ofthe rod, as set forth.

2. A door-check, comprising an upper and lower housing having alinedbearings and adapted to be fastened to the door, a checkbolt slidable inthe lower housing, a springpressed rod mounted to slide in saidbearings, and a lever in the'upper housing and having an elongated slotfor the passage of the pivot of the lever, to allow the lever to swingand to slide on the pivot, as set forth.

3. A door-check, comprising an upper and lower housing having alinedbearings and 'adapted to be fastened to the door, a checkbolt slidablein the lower housing, a springpressed rod mounted to slide in saidbearings, a lever in the upper housing and having an elongated slot forthe passage of the pivot of the lever, to allow the lever to swing andto slide on the pivot, and a support on said upper housing for the freeend of the lever to rest'on when in an uppermost position, as set forth.

Ll. A door-check, comprising an upper and lower housing having alinedbearings and adapted to be fastened to the door, a checkbolt slidable inthe lower housing, a springpressed rod mounted to slide in saidbearings, a lever in the upper housing and having an elongated slot forthe passage of the pivot of the lever, to allow the lever to swing andto slide on the pivot, a support on said upper housing for the free endof the lever to rest on when in an uppermost position, and a springsecured to the upper housing and adapted to press said lever when in anuppermost position, to hold the lever to its seat on said support, asset forth.

5. A door-check, comprising an upper and lower housing, a spring-pressedrod slidable in said housings and provided with a slot, a check-bolt, anoperating-lever for the rod, and a removable device for temporarilyholding the parts in position when the check-bolt is withdrawn, saiddevice consisting of a forked locking-plate for straddling said rod atthe slot therein, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

GEORGE STUBBS.
